Issue/Introduction

How to Reconfigure vRNI 6.2  Cluster Deployment to enable flow based discovery on large number of VMs (> 3K)

Environment

VMware vRealize Network Insight 6.2.x

Resolution

Perform the Below steps to validate the current configuration from vRNI UI

1) Go to setting page ->  Overview and Updates -> Platform Capacity -> Check capacity of Devices

Refer to UI as per the below screenshot:

1.  If capacity > 50 then do nothing => Existing deployment support Flow-Based Application Discovery for the large number of VMs (>3 K) => No action required.
2. If capacity <=50 then follow the below mentioned steps to reconfigure the deployment

Follow below steps to do vRNI deployment reconfiguration:

• SSH login as support user to platform1
  • These steps can be performed only from P1
• Change user to ubuntu (sudo su ubuntu)
• Run following command - python3 /home/ubuntu/build-target/deploymentmanager/change_deployment_config.py
  • This will execute an interactive program with the following options

1. Enter deployment def ID to apply
2. List deployment defs for current config
3. List deployment defs for another config
4. exit

• • Choose the option to list available configs (Option 2)
    • This will list currently applied config as well as configs that can be applied (see sample output)
    • The list also has a description of the config to help in understanding the status of service and limits in the config
  • Get the id of config available to be applied (e.g. PX3C3E in sample output)
  • Apply the config and wait for the completion (Option 1)
    • It takes around 5 to 10 minutes
• Logs of this process are present in file: /home/ubuntu/logs/deployment_change.log

See the Sample output of changing config on a 3XL setup:

support@platform1:~$ sudo su ubuntu
ubuntu@platform1:/home/support$ python3 /home/ubuntu/build-target/deploymentmanager/change_deployment_config.py
